POOL AND BILLIARD TABLE LEVELER.

Application led July 27,

To all whom 'it 'ma-y concern:

e it known that we, Jol-IN J. Moons I.ind Pimmir C. MCMMION, citizens of the United States, residing at South Charleston, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Pooland Billiard Table Levelers; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to the class of games and toys, and more especially' to pool and billiard tables; same is to produce an improved device for elevating the legs of such a table so as to cause its surface to be truly level. This object is accomplished by the specific construction of the leveler hereinafter more fully described and claimed, and as shown in the accompanying drawings wherein` Figure 1 is an elevation of the lower end of a billiard or other table-leg showing one of our improved levelers beneath it; Fig. 2 is an enlarged transverse section through the leveler propel', and Fig. 8 is a similar section on the line 3-3 of Fig. 2; Fig. 4 is a perspective detail of the various wedge members.

In the drawings the letter L designates the leg of a pool or billiard table such as is usually coi'inected with the table body itself by some screw means so that. the leg or support can be lengthened while its lower end remains upon the floor F. Between the leg and lloor we propose to insert our improved Ieveler which is of any desired materials, proportions, and sizes, excepting that by preferenceit-will he made of metal and will have an area of about two and tl'n'ee-quarters inches square and a normal height of about an inch and one quarter although it` will be susceptible of elevation to a greater. height. In use this deyiee is inserted under the leg of the table and squarely upon the floor, and, after four of them have been put into place and a spirit level laid upon the tabletop, the various levelers can be adjusted so as to bring said top to a truc horizontal.

Coming now more particularly to the details of the present invention, we provide outer'and inner boxes, or more properly speaking shells, a set of Wedges housed therein. and means for adjusting the wedges so Specification of Letters Patent.

that the outer shell shall be raised telesco ically over the inner shell. The latter Iby preference comprises a fiat base 1, two oppositely disposed upright sides 2, and two ends 3 rising to about the same height as the sides and one of them provided with a deep notch 4; and the outer shell comprises a closed flat top 11, two oppositely disposed sides 12 spaced apart a sufiicient distance to permit them to pass over the sides 2 of the base member, and two ends 13 of which one has a notch 14 somewhat wider than that numbered 4. In assembling the two members or shells their closed ends overlie each other and the notched end of the outer and upper shell normally over-lies the notched end of the inner or base shell so that no dust and dirt can accumulate within the device. In order to prevent these two shellsfrom being entirely disconnected, while yet permitting the vertical movement of the outer upon the inner, we provide the sides of the outer shell in their inner faces with upright grooves l5 into which lit outwardly projecting studs 5 on the inner shell, and the slidable engagement of the studs with the grooves prevents the members or shells from being separated from each other horizontally While permitting the upper shell to risc and fall. Taking through the sides of the outer shell are two screws 1G whose inner ends project into the grooves 15, and these screws may be set up so that as the outer shell rises they will strike beneath the studs 5,011 the inner shell and will prevent the two members or shells from being disconneeted vertically, while yet permitting them to be purposely disconnected when the screws are retracted. Thus is built up what might be called the box-shaped casing composed of two members or shells which cannot become accidentally disconnected and whereof the outer or upper shell is capableof vertical movement relatively to the inner or lower shell". Vtthin the box-shaped casing or housing thus built up We assemble a series of wedges or blocks which are also preferably of metal. The base block 20 has a fiat; bottom 21 and two-converging sides 22 forming its top and meeting at an angle 23, through which at its center is formed a. transverse notch 24. The cap block 30 has a flat top 31 and a beveled lower face 32 Whose angle to its top is the same as that of either side 22 to the bottom 2l of the `block described above,

and through the body of this cap block is formed a notch. 34 which l runs parallelwit'h its top face 31 and opens l ontits upright base end 35. rlf`he thirdl block 40 is wedge-shaped, its inclined upper l face 41 and inclined lower tace 1l-i! each standing at the same angle to a horizontal as do'the inclined faces ot' the other blocks just described; and throughout the length of this block extends a threaded hole ttl which opens at one end through the angle 43 l of the wedge and at the other end through l its upright base end 45. When these several l blocks are assembled with their inelinedl faces in Contact, they make up a composite wedge or elevating member which is reel tangular in side elevation as illustrated and whose horizontal dimensions '-are just such l that it will tit accurately and. neatly within l the inner shell or casing member described l above. l The numeral 5() designates a screw whose l threads are such that they will engage those i in the hole 44 of the wedge block 40 and whose head 5l is made angular for the rel ception of a wrenrh or suitablrl tool. Just under the head is an enlarged collar 52' which, when all parts are in place, against the outer face oi' the end 3 of the i hase shell, the shank ot the screw 5U exl tendine;` through its notch ft and its threads l taking: into the hole lt. and the head 5l of l the screw standing;l on the outside of the en 1 tire device where it may be reached by a wrench or suitable tool. i The parts having.r been assembled as set l i'orth. this improved leveler is inserted unl der the loo; L or under any other artielol which it is desired to raise. and the same will be firmly sumiortrd 'without permitting,r l any vibration. ll'ben it is desired to elevate the member .supported thereby, the 'L screw 50 is turned in the proper direction to l draw the u'edfre bloeit 'l0 toward the upright l base end 35 ot the cap blot-lt fit). and in its movement in that direction its upper laee 4l l slides along; the lower tare il? oi the rap bloei: and its lower laee `l slides along one i oi the sides 32 of the base bloeit while the lower l'aee :l2 o't' the cap bloeit where it rests l upon the other lside 2Q of the base block is l soon lifted out of contact with the same by the eutranre ot" the wedge. vl`he upright walls which compose the ends 5% and 13 of the two sliellsuirovi-nt the lutin-oper movel ments of theI wedge members while bringt adjusted With this screw, and the other walls or sides 9 and l. ofvsaid shells stand adjacent" the ends of said block members although 4the screw passing through the hole in the bloehY 10' and through the notches 24 and ill in the other blotks will prevent their lateral discounts-thm or separation. l'lavinelr elevated lite outer or rap blot-lt' as t'ar as necessary to levellhe billiard table or other article, the user has only to remove the Wrench or tool from the square head 51. of the screw and leave the parts at rest. Meanwhile the studs 5 on the inner shell have ridden up the grooves l5 within the outer shell, and it has been impossible for these two shells to become disconnected laterally. From time to time the adjustments may be changed asdifferent conditions will. requirefand it will be clear that a reverse movement of the screw will cause a descent of the article or member to be leveled just as a right turn on the screw will cause its ascent.

hat is claimed as new is:

In testimony whereof wo have hereunto set our hands in presence of two subscribing 15 witnesses.
